2

Sealing refers to heat transfer technology.

Seals are known for a package of plates, for example, in a heat exchanger, containing a shaped · elastic element installed in the groove of the plate.

The purpose of the invention is to simplify manufacturing technology and improve reliability. IQ

This is achieved by the fact that the elastic element on the side of the groove of the plate has protrusions, for example, of cylindrical shape, entering holes made in the groove of the plate, with an interference fit to form when assembling the package at * 5 ends of the protrusions passing through the holes, thickenings exceeding the size of the holes .

Figure 1 shows a cross section of a shaped elastic element with a protrusion; figure 2 is a cross section of the groove of the plate with a hole; Fig. 3 - assembly of a package of plates with seals.

The seal for the package of plates contains an elastic shaped element 1 with a cylindrical protrusion 2, which is inserted into the groove 3 of the plate having an opening 4. Due to the fact that the cylindrical protrusion 2 enters the hole, when assembling the package when compressing adjacent plates at the ends of the cylindrical protrusions 2, passing through the holes 4, thickenings are formed. They keep the acquired shape in a free state, which additionally holds the shaped elastic element during disassembly of the heat exchanger.

Seal refers to heat exchange engineering. Seals for a stack of plates are known, for example, in a heat exchanger, comprising a shaped-resilient element installed in the slot of the plate. The purpose of the invention is to simplify manufacturing technology and improve reliability. This is achieved by the fact that the resilient element on the side of the groove of the plate has protrusions, for example, of a cylindrical shape, which enter the holes made in the slot of the plate, with a tension to form during assembly of the package at the ends of the protrusions that pass through the holes, thickenings holes. Figure 1 shows a section of a shaped elastic element with a protrusion; figure 2 - cross section of the groove of the plate with a hole; FIG. 3 shows an assembly of a pack of plates with seals. The seal for the poster plates contains an elastic shaped element 1 with a cylindrical protrusion 2, which is inserted into the groove 3 of the plate having an opening 4. Due to the fact that the cylindrical protrusion 2 enters the hole when the package is assembled during compression of adjacent plates at the ends of the cylindrical protrusions 2 that have passed through the holes 4, thickenings are formed. They retain the acquired shape in the free state, which additionally keeps the shaped elastic element of 1 t when disassembling the heat exchanger. Claims for Packing. plates, for example, in a heat exchanger containing a shaped elastic element installed in the groove of the plate, about t l and -. In particular, in order to simplify the manufacturing technology and improve reliability, the resilient element on the side of the slot of the plate has protrusions, for example, of a cylindrical shape, which enter the holes made in the slot of the plate with tension to form during the assembly of the package at the ends of the projections passing through the holes, bulges, exceeding the size of the holes.
